The Flash: Every character ranked from worst to best

25. Cicada

Cicada was arguably The Flash‘s most exciting villain at the beginning of his run. He was terrifying in his hooded black cloak and his oxygen-like mask as he massacred metahumans in Central City out of revenge, but the show quickly dropped the ball with him.

The character was doomed to repeat the same cycle in every single episode of the lengthy fifth season, showing up to kill someone, confronting Team Flash only to get defeated in battle. The most ridiculous thing is that the one-note villain was then allowed to escape every darn time.

There were flashes of brilliance in Orlin Dwyer’s arc, but the show waited too long to explore that. Thus, we were left with the mumbling, groaning, and disappointing shell of a character for most of the season. And that’s a huge letdown on all fronts.

24. Mirror Monarch

When we first met Eva McCulloch’s Mirror Monarch on The Flash season 6, we were pretty excited about what she had in store. DC’s Mirror Master was one of the few Flash villains that the series hadn’t adapted properly (outside of a loose adaptation in season 3), so Eva’s arrival was intriguing.

Efrat Dor certainly gave a convincing performance, making it easy to root for Eva early on, and she portrayed the sinister nature of the character in later episodes extremely well. However, the character felt unusually underdeveloped (the graphic novel approach limited audiences’ time with her) and the resolution of the storyline in season 7 undercut all of her momentum.

She was very good, but compared to other villains, she fell pretty flat unfortunately.
